Authentication for Redis about developer

[etehtsea]

Actually, there is a way to provide the password through address url.
If a redis instance has:

requirepass "hello world"

trigger = {type = "redis", address = "redis://:hello world@localhost:6379"}

will work (I've tested against examples/redis-rust).

Ooooh this is great!
Thank you!

I will leave this issue open, as I'd like to track adding this to the documentation as well.

That being said, we would still want to be able to somehow use a secret here as well, but this is a great starting point, thanks, @etehtsea!

We do now show an example in docs around hard-coding the password in the redis addres: https://developer.fermyon.com/spin/redis-trigger#specifying-an-application-as-redis.

As @radu-matei mentions, it would be ideal to use a secret here. I was actually under the impression that we could use Spin's dynamic/runtime config approach to do so, but now realize that it isn't yet possible, as it doesn't appear that interpolation is supported in the address field of the trigger section of the spin.toml. Perhaps others can check my understanding here. Assuming it is not yet possible, do we want to track this work in this same issue or create a new one?
